Intel Says Patches For Chip Issue Could Have Flaws

Months passed before the problems were disclosed to the public. The fixes reportedly rendered a smaller number of systems unbootable. However, users running Web applications with complex Javascript operations might see a 10 percent reduction. The recently launched Intel Coffee Lake flagship, the Core i7-8700K, comes off 6% worse in SYSmark, a 4% decrease in PCMark 10, and no change in 3DMark Sky Diver.

The results for 7th Gen Kaby Lake-H processors with SSDs is similar to that of 8th generation processors. The complaint cited reports that Intel had been warned of the problem.

Users of systems with affected AMD processors should make sure the appropriate firmware and software updates are applied when they are made available by Microsoft and AMD.

Intel has confirmed a bug in its fix for the Meltdown and Spectre vulnerabilities which can cause random reboots, on top of the performance impact which has seen some server workloads seriously impacted. In a post on its website, the chip firm goes into how it plans to deal with these problems.

Contrary to Intel's protests, the potential risk from Meltdown is due to a design flaw, Thompson also noted.

The flaws affect virtually all computing devices running on chips manufactured by Intel, AMD and ARM, although the worst - called Meltdown - largely just affects Intel.

GPZ Variant 2, is the second variant of Spectre. These techniques potentially make items in kernel memory available to user processes by taking advantage of a delay in the time it may take the CPU to check the validity of a memory access call. Since exploiting many of these issues requires a malicious app to be loaded on your Mac or iOS device, we recommend downloading software only from trusted sources such as the App Store.

Meltdowns, suspect share dealing and class-action suits, it's been an interesting 2018 for Intel so far, and it doesn't seem to be getting better quickly. However, it is believed that this threat will be contained with an operating system patch.

News first emerged that Intel's processors contained security flaws, later named Meltdown and Spectre, affecting almost every modern computer.

As well as triggering undesirable behaviour the Spectre patches are degrading machine performance, particularly for older processors.
